Question SSDs no longer recognised by MSW10 after Update - please help?

Mar 16, 2021
Hi all,
After a bigger Windows 10 Update (2020H2) my OS stopped recognising my three SSD SATA drives (M.2 boot drive still works fine). Yesterday, prior to the update, all drives still worked just fine. All drives are recognised by the BIOS, but the SATA drives are not recognised by Windows explorer, disk manager or device manager. My driver manager software (Driver Hub) notes that the SATA driver needs an update, tries to update but fails. Automatic driver update in Windows just tells me that the most up to date driver is installed even though the driver is from 2015. The AMD website informs that the SATA driver which comes with Windows is the right one to use.
This has happened to me before and I ended up reformatting all my drives and reinstalling windows to get the SSDs working again. I would rather like to avoid going through that again. Does anybody have any tips on what else I could try?

Small update: Updating the Chipset drivers from Gigabyte and/or AMD website made no difference. Returning MSW Build to Version 10.0.18363 Build 18363 made the drives reappear straight away. What could this be?

With many thanks in advance.
